Skype is a voice and video chat app for PC and mobile which lets users make cheap or free calls to other Skype users or telephone numbers. Microsoft bought Skype in 2011, so it’s no surprise that the company was working on a Windows Phone app to join the Skype apps for Android and iOS.

Skype for Windows Phone has been available as a public beta since February. This weekend the company lifted the beta label. You can now download Skype from the Windows Phone Marketplace.

Skype for Windows Phone 7

You can use Skype to make calls over WiFi, 3G, or 4G networks. The app is availabel in 18 languages, and calls to other Skype users are free.

The app requires Windows Phone 7.5 or later — and it also requires 512MB of memory or more. That means some of the new low-end smartphones running Windows Phone 7.5 such as the Nokia Lumia 610 and ZTE Orbit won’t be able to run Skype.
